핫 스왑 촉진을 위한 확장 가능한 배터리 아키텍처에 관한 연구

A study on scalable battery architectures for hot-swap facilitation

High power and energy applications of battery require a large number of batteries to be connected in series, parallel or mixed configurations. The reliability or these batteries is improved by making them tolerant to faults i.e. by bypassing the fault cells and adding new cells to compensate the voltage and current requirement. The addition or removal or cells may cause the current stress on other healthy cells. The estimation and control or this current stress is one or the technique proposed by other researchers. This study intends to identify a suitable scalable configuration which can either avoid or reduce the efforts on the estimation and control of stress current. In addition, this paper will explore the issues associated with hot-swap.
